centos7手动编译安装Libvirt常见问题

由于功能需要，体验了手动编译安装Libvrt,还是碰到了不少问题，这里总结如下仅限于centos7：

1、configure: error: You must install the pciaccess module to build with udev

解决方案：yum install libpciaccess-devel.x86_64

 

 

2、configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt

解决方案：yum install device-mapper-devel

 

3、configure: error: libnl-devel >= 1.1 is required for macvtap support

解决方案：yum install libnl-devel.x86_64

 

 

4、configure: error: You must install the libyajl library & headers to compile libvirt

解决方案：yum install libxml2.x86_64  yum install libxml2-devel.x86_64

              yum install yajl.x86_64 yajl-devel.x86_64

 

5、 error: Failed to connect socket to '/usr/local/var/run/libvirt/libvirt-sock': Connection refused

 

这个是virsh连接libvirtd守护进程的时候容易出现的问题，根本原因是libvirtd服务没有启动

解决方案：libvirtd -d

 

6、启动Libvirt出现问题：libvirtd: error: Unable to obtain pidfile. Check /var/log/messages or run without --daemon for more

解决方案：

（1）查找到libvirtd.pid文件，根据libvirt的安装不同，位置可能不同：

$ sudo find / -name libvirtd.pid
[sudo] password for cloud: 
/usr/local/var/run/libvirtd.pid

（2）删除：$sudo rm /usr/local/var/run/libvirtd.pid

（3）启动：$sudo libvirtd -d
